    专利说明:

    The invention relates to mechanical engineering. A compressed air dryer is known that contains two tanks with a desiccant, communicated by a ground opening, a control valve, alternately communicating one of the reservoirs with a line for supplying dried air, and a three-way valve, the closure of which is located in the connecting channel, connected between them, and clamped to one of the saddles by the end ends of a spring-loaded valve stem, which is located perpendicular to the locking organ and overlaps the additional channel, which informs Yelnia channel to the environment, wherein the valve stem associated with the sensitive elements that drive the operating kotorog chamber communicates with the inlet and the other chamber is placed a spring. A disadvantage of the known valve is the relatively long axial movement of the locking member of the three-way valve, which requires the release and re-locking it in a new position, which increases the size of the device and reduces its efficiency. The purpose of the invention is to reduce the size of the drier. This goal is achieved by the fact that in a compressed air dryer containing two tanks with a desiccant, communicated by a throttle orifice, a distribution valve alternately connecting one of the reservoirs to the main supply of dried air, a three-way valve whose shut-off element is located in the connecting channel that communicates with each other tanks, and pressed to one of the saddles by the conical end of a spring-loaded valve stem, located perpendicular to the locking member and blocking the additional an inlet connecting the channel with the environment, the valve stem being connected to the sensing element of the actuator whose working chamber communicates with the inlet, and a spring is placed in the other valve two recesses are made in the locking member, the valve stem meets, and the valve stem is missing 12 through an additional channel in which the sealing ring is installed, and is provided with an annular collar that forms a shut-off pair with the sealing ring when the control valve is switched. In addition, the locking member can be made cylindrical and on its side surface there is a longitudinal groove connecting the grooves, the groove depth being less than the depth of the grooves. Fig, 1 shows a compressed air dryer, a general view; in fig. 2 — node I in FIG. 1. The dryer contains two tanks 1 and 2, each of which has a support base 3 and is cylindrical with a domed upper condom. Each tank has a central axial separation wall 4, dividing the cavity of the tank into two chambers 5 and 6i. Windows 7 are made in the separation wall for connecting two chambers to each other. The lower end of each chamber is closed by a wall comprising two perforated plates 8, spacers 9 and filtering material 10, for example, foam polystyrene. Each tank is filled with a granular desiccant .11, which is held under pressure by means of a spring-loaded bottom wall so as to maintain it in a packed state in the tank. Tanks 1 and 2 are connected to each other through a control valve 12, alternately connecting them to the compressed air supply line (not shown) and through the OR element with the output line (not shown). The tanks 1 and 2 are also communicated with each other by a throttle hole (not shown). In addition, the compressed air dryer contains a three-way valve, the locking member 13.to which is located in the connecting channel 14, which interconnects the tanks. The locking member is pressed against one of the seats 15, 16 by the conical end 17 of the valve stem 18, which is included in one of the recesses 19, 20 on the locking member. The rod is located perpendicular to the locking organ and is passed through an additional channel 21, jointly connecting channel 14 with the environment. In the additional channel 21, a sealing ring 22 is installed, and the stem is provided with an annular collar 23, which forms a shut-off couple with a sealing ring when switching the distribution valve. In addition, the valve rod 18 is connected to the sensing element 24 of the actuator, the working chamber 25 of which communicates with the inlet opening 26, and the spring 27 is placed in the other. The locking member can be cylindrical with the longitudinal groove 28 on the lateral surface of the communicating recess less depth depths. Compressed air from the compressor is supplied to the left tank 1 through the distribution valve 12, which is under the action of air pressure in the extreme right position with the leftmost position of the shut-off valve 13 of the three-way valve. In the tank 1, the pressurized air passes from the base 3 of the tank through the filtering material 10 to separate particles of water and oil, then up and down through the granular desiccant 11 in two chambers 5 and 6 of the tank. The compressed air is thereby dried and exits the bottom of chamber 6 of the reservoir through an outlet opening communicated with the outlet line by the OR element. In this case, a small part of the dried air through the throttle opening, which connects the tanks, enters into the tank 2, from which it enters the environment through a three-way one. the valve and the additional channel 21. As a result, the desiccant in the tank 2 is dried and its preparation for operation. When a control signal is supplied to the actuator inlet 26, the valve rod 18 moves away from the locking member 13 of the three-way valve, while the collar 23 closes the additional channel 21 and separates the tanks 1 and 2 from the environment, and the conical end 17 releases the locking a three-way valve organ, an outlet from the orifice 20. Under the action yes: occurrences in the tank 1, the locking member 13 moves to the right position. The pressure in the tanks t and 2 is equalized. After the control signal is removed, the locking member is pressed against the saddle 15 by the conical end face t7, and jpesepByar 1 is communicated through an additional hole with the surrounding environment. At the same time, pressure in tank 1 somewhat decreases, and the control valve switches to a new position, informing tank 2 prepared for operation with reservoir 2 to supply air to be dried. Tank 1 will be prepared for operation by air coming from tank 2 through the throttle hole. At the moment of switching the distribution valve, the end of the valve stem is placed in the longitudinal groove 28, which prevents the valve from turning, of the valve member at the moment of switching. The implementation of the distribution valve in the proposed way allows to round up the dimensions of the dehumidifier. I
